VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 294,190, dated February26, 1884l Application filed December 1.0, 1883. (No model.) i

To @ZZ whom, t may concern:

`body or box of the vehicle.

Be it known that I, GHRIsToPHER G. BRAD- LEY, of the city of Syracuse,in the county of Onondaga, in the State of New York, haveinvented a newand useful Improvement in Carriage-Sprin'gs, of which the followingis aspeciiication.

rIhis invention relates to an improvement in that class ofcarriage-springs which are coinposed of side springs and end springsconnected together at their ends by couplings; and the object of thisinvention is to connect the side springs to the body orbox of the wagonor carriage in such manner that a secure connection is establishedbetween the springs and the box, while the side springs are not weakenedto any appreciable extent, and permitted to move freely as the body orbox rises and falls.

My invention consists, to that end, of the improvements which will behereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 represents a side ,elevation ofmy improved carriage-spring. Fig. 2 is a top plan view thereof, with theoutlines of the box or body shown in dotted lines. Fig. 3 is a verticalcross-section, o n an enlarged scale, of the side spring at a pointwhere it is attached by the clip to the Fig. is a longitudinal sectionat right angles to Fig. 3. Fig. 5 is a side elevation of the clip. Fig.6 isa perspective view of the coupling whereby the ends of the side andend springs are connected.

Like letters of reference refer to like parts in the several gures.

A represents the body or box of the wagon; B B, the side springs; G C,the end springs, and D the couplings whereby the ends of the end springsare connected with the ends of the side springs. The couplings D areeach provided with two holes arranged in different parallel planes atright angles to each other, and adapted to receive trunnions b c, formedat the ends of the side and end springs, and secured by screw-nuts b c,whereby the ends of the springs are securely connected and each springis permitted to move freely as it is bent. E E are cross-bars secured tothe under side of the body or box A of the vehicle, and connected to theside springs, B, by clips F,which latter straddle the springs and aresecured thereto by screw-nuts f. The clips F are provided with studs orprojections (,which enter openings lzy in the springs, whereby the clipsare held against longitudinal displacement on the springs, and thesprings are at thedsame time dle thereof. lIhe studs g have sufficientplay in the openings h, as represented in Figs. 3 and 4, to permit oftherequisite rocking movement of the side springs within the clips F. Thelegs of the clips F are provided with shoulders t', against which thecross-bars E are drawn by the screw-nuts f, so that the pressure of thescrewnuts is received by the vshoulders z' when the screw-nuts aretightened, leaving the springs free in the clips, and permitting thesprings to play freely during the movements of the vehicle. The sidesprings are by this means connected with the body or box of the vehiclein such manner as to permit of the requisite free movement ofthe sidesprings within the fastening devices whereby they are attached to thebody; and as the side springs are connected by a movable joint with theend springs, each `member of the system of springs on which the bodyissupported moves freely in adapting itself to the movements of thecarriage-body, and all the members are at the same time permanentlyconnected, whereby a strong, substantial, and easy-riding spring isproduced.

I claim as my invention- 1. The combination, with a carriage-body andcarriage-spring, of a clip rigidly secured to the carriage-body andconstructed with a projection or stud fitted loosely in a recess in thespring, whereby the spring is held in place, while being permitted torockin the clip in adjusting itself to the movements of thecarriagebody, substantially as described.

- 2. The combination,with the carriage-body,

of end springs, C C, side springs7 B B, oonneeted with the end springsby couplings D, and clips F, secured to the Carriage-body and havingprojeotions g, loosely fitted in openin gs or depressions h in the sidesprings,\v1iere by the springs are heid in platee, und tt the saine timepermitted to inovein the Clips, substa-ntially as described.

Vitness my hand this 26th day o1" November, 1883.
